“Caroline was a brilliant actress and in her role as Liz Shaw, a tremendous co-star for Jon Pertwee in his first year as the Doctor. She was not just a sidekick but a scientist in her own right and a match for the universe’s number one know-all. The Doctor’s companions should never be his assistants – they’re the people who keep him on his toes, and that’s what Caroline did. From everyone at the show, our thoughts go out to Caroline’s family.”

Caroline John passed away 5th June and is survived by her husband Geoffrey Beevers and three children.

Everyone has a favourite Doctor and mine - just for his honesty, his fairness and his ability to not notice the Master's awful, awful disguises/anagrams (Sir Gilles Estram!?!) - has to be the Fifth Doctor, Peter Davison. The stories didn’t serve him as well as his acting served those stories.
